Embodiment
Now with reference to the accompanying drawings comparatively detailed description is carried out to the present invention, as shown in Figure 1, a kind of High Precision Automatic batching control system, comprise Weight acquisition module, signal processing module, control module and module is set, the weight signal of described Weight acquisition module acquires electronic scale weighing material sends signal processing module to, describedly module installation canonical parameter is set and sends described signal processing module to, gather weight signal and setting canonical parameter comparison process after signal processing module send control signal to control module, described control module controls slightly to throw valve by I/O mouth according to the difference of control signal respectively, thin throwing valve or discharge valve are opened or are closed.
Also comprise alarm module, described control module sends alerting signal according to the operation irregularity situation of each valve to signal processing module, and alerting signal shows by arranging module by described signal processing module.
Also comprise data processing enquiry module, the working condition that described control module gathers each valve passes to described signal processing module, and the operating condition signals of each valve is passed to data processing enquiry module and carries out query display by described signal processing module.
Described Weight acquisition module is weight transmitter, and described signal processing module is a PLC, and described control module is the 2nd PLC, and the described module that arranges is touch-screen.
Described weight transmitter model is GK409, and the model of a described PLC is S7-300, and the model of described 2nd PLC is S7-200, and the described model arranging module is MP277 touch-screen.
The model of described data processing enquiry module is WINCC.
Described electronic scale has 4, and each electronic scale controls 4 kinds of materials.
For the ease of joining the actual formulation monitor of powder and management, carrying out communication between native system and host computer and carrying out control and management by host computer.
Concrete control flow is as follows: terminate after T0 time delay hopper is stable when a certain material of configuration is reinforced, whether this material of automatic discrimination is overproof, if not overproof, automatically continue next material and feed in raw material, if overproof and be negative error time, just automatically carry out crawl feed supplement, item number relay corresponding during feed supplement and slow relay action a period of time, disconnect a period of time, then automatic discrimination whether feed supplement to allow error range in, if in allowed band or error be principal-employment, stop feed supplement, if do not reach yet in tolerance, continue crawl feed supplement until error is less than franchise.Excessively become positive error to prevent from making up the difference, the relay crawl time calculates according to error amount size, while overproof according to what calculate before feed supplement, system calculates overproof amount automatically, the overproof amount of auto modification, automatically adjusts batching control parameter next time.
When between actual blanking value SP and setting blanking value SD, deviate is negative value Q, automatic calculating feed supplement time T1=KQ, system carries out automatic feeding (having mended material calculates T1 value automatically at every turn) according to calculated T1 time length, till actual blanking value being compensated to setting blanking value.Simultaneously after first time, batching terminated (before non-feed supplement), when between the actual blanking value SP of system and setting blanking value SD, deviate is negative value Q, system calculates new batching modified value XZ=XZ0-KQ automatically, when between actual blanking value SP and setting blanking value SD, deviate is positive Q, new batching modified value XZ=XZ0+KQ
Screen is upper can be set material and slightly to prepare burden definite value, definite value of carefully preparing burden, and feed intake end T0 stabilization time, feed supplement time T1. is when feed proportioning system blanking, and when the material set point that touch display screen shows and actual blanking value difference XZ0, system stops batching, after the T0 of delay adjustments, read actual blanking value SP:
(1), when SP is less than setting blanking value, system automatic feeding, after charging time arrives feed supplement time T1, stop feed supplement, after the T0 of system delay setting, read actual blanking value SP, if actual blanking value is less than setting blanking value, continue feed supplement, until SP is more than or equal to setting material value.System finishing feed supplement state, simultaneity factor stops batching in first time, after time delay T0, read actual blanking value SP, when SP is less than setting blanking value, system calculates deviate Q between actual blanking value SP and setting blanking value SD automatically, utilizes formula XZ=XZ0+KQ, calculate XZ value, and then the modified value of amendment batching automatically.
(2) when SP is greater than setting blanking value, system calculates deviate Q between actual blanking value SP and setting blanking value SD automatically, utilizes formula XZ=XZ0-KQ, calculate XZ value, and then the modified value of amendment batching automatically, when XZ is greater than SP60%, XZ=SP60%.When XZ is less than SP0.5%, XZ=SP0.5%.
Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the scope of the invention change and improve, and all should still belong within this patent covering scope.
